This is really tough. Dirty drivers and knobs are such a challenge on this track even without the shortcut. The 🤬 even got me to jump over to the dark side yesterday, took the shortcut. I'm baffled by how someone is still playing GT6 in 2016 but doesn't get the hell out of the way when someone substantially faster comes along. Particularly very early on in a race.
It would take so little effort to close all possible shortcuts like these, certainly for GT Sport and GT7. Hay bails, tire walls, skimpy little fence, invisible wall, it doesn't matter. Have an intern spend a few weeks, find them all, fix them all. Invisible wall might be best because it's minimal effort for maximum humiliation of cheaters. On second thought, best would be invisible corkscrew ramp (no landing ramp, no automatic reset of the car onto the track.)
If PD won't set up the penalty system properly, they need to at least take away the opportunities to cheat egregiously. Or do the corkscrew ramp thing.
On third thought, the corscrew would turn the servers into giant destruction derby's of people trying to hit the jumps and land on all 4 wheels. Scrap that.
